Installing a RAID adapter battery or flash power module

Use this information to install a RAID adapter battery or flash power module in the server.

When you install any RAID adapter that comes with batteries or flash power modules, it is sometimes necessary to install the batteries or flash power modules in another location in the server to prevent the batteries or flash power modules from overheating. Depending on your server model, a battery must be installed remotely near the optical drive cage or the backplane.

Note

RAID adapter battery or flash power module is only supported in the 2.5-inch models.

Read the safety information in Safety and Installation guidelines.

If you are installing an optional device in the server, you need to slide the server out from the rack enclosure, turn off the server and peripheral devices, and disconnect the power cords and all external cables.

To install a RAID adapter battery or flash power module in the server, complete the following steps:

1. Remove the cover (see Removing the cover).
2. Remove the PCI riser-card assembly (see Removing the PCI riser-card assembly).
3. Install the ServeRAID adapter in the PCI riser-card assembly (see Installing an Lenovo ServeRAID SAS/SATA controller).
4. Connect one end of the cable to the connector.
5. Make sure the relevant cables pass through the cable clips.

   Attention

   Make sure that the cable is not pinched and does not cover any connectors or obstruct any components on the system board.
6. Remove any cable covering or obstructing the holder before opening the holder.
7. Install the battery or flash power module:
   1. Remove the retainer.
   2. Release the retention clip in the open position.
   3. Align the cable connector with the slot on the holder. Place the battery or flash power module into the holder and make sure that the holder engages the battery or flash power module securely.

      The positioning of the remote battery or flash power module depends on the type of the remote batteries or flash power modules that you install.
   4. Connect the other end of the cable to the cable connector on the battery or flash power module.
   5. Lower and press down on the retention clip until it snaps in place to hold the battery or flash power module firmly in place.
   6. Install the retainer.
8. Reinstall the PCI riser-card assembly (see Replacing the PCI riser-card assembly).
